brian printed it out and gave me the only copy, and then his computer was infected with a virus that destroyed all his files. it had diagrams for mens et manus and attack of the kraken. i accidentally spilled coffee on it and set it on fire and now it's all gone. he's quite vexed with me.
in seriousness. the minute, the second, that gallery origami house is going to print a book, it announces it. heck, any books that are going out of print it announces. the minute, the second that brian chan's book is headed to the presses, they will say and there's no reason to believe that anyone on this site will know before that. there's already been a thread on it and it's already been discussed. joisel's book will be published first. especially with his passing, i imagine they will make it a priority over all authors. origami insects II was their last publication and that was several years ago; one shouldn't be shocked if there is a similar interval between joisel's book and chan's.
